Hi Meenakshmi. You can certainly create "What's This" type
help in both CHM and HLP files. You just need to create a map file
that maps the application call to a specific help topic. How your
Oracle and D2K applications do this is down to the developers.
Normally all you'll have to do is give them a map file containing
the mapids and they should do the rest.

Yes you can Meenakshmi. It works in a similar way to HTML
Help or Winhelp. The only difference is the call from the
application which uses a different call syntax. Your developers
should be able to help set up the application with this. From a RH
perspective, just setup the map file in the normal manner and
supply the map file to your developer - unless they've already
provided you with a map file that is

You may not find the exact content for the code calls, but
the links should help you get on the right track. There is also a
lot of useful information specifically for developers in Robohelps
own online help.
